 The Sun-fish has been generally mentioned as remarliable 

 for its phosphorescence ; but this specimen did not exhibit 

 that phenomenon so distinctly as a Haddock or a Herring." 

 Pennant repeats Brunnich's account, that between Antibes 

 and Genoa he saw one of this species lie asleep on the sur- 

 face of the Avater : a sailor jumped overboard and caught it. 



Mr. Couch says the Short Sun-fish is migratory, keeping 

 probably at the bottom, and feeding on seaweeds in its ordi-

 above the water, floating with the tide. Mr. Couch has 

 known the Sun-fish make powerful but awkward efforts to 

 escape when attacked, bending and directing its motions in 

 various ways. 



The figure here given, and the description, are taken from 

 a preserved specimen in the Museum of the Zoological So- 

 ciety. This is the smallest example I have seen. It mea- 

 sures but fourteen inches from the point of the nose to the 

 end of the body ; the breadth of the caudal fin two inches ; 

 the depth of the body eleven inches and a half : the length 

 of the dorsal fin eight inches ; of the anal fin, seven inches 

 and a half: the extension of skin connecting the fin-rays 

 rather thick. The mouth small ; the branchial aperture just 

 in advance of the pectoral fin, small and oval ; the vent just 

 before the anal fin ; the caudal fin occupying the whole space 

 between the anal and dorsal fins, and attached to the pos- 

 terior vertical edge of the body as by a long hinge ; the sur- 

 face of the body in this young specimen but slightly rough- 

 ened, and somewhat wrinkled. The colour of the upper 

 part of the body dusky bluish grey ; the lower part olive 

 brown. The fin-rays in number are —
